1. Evolution of Mimicry and Aposematism Explained: Salient Traits and Predator Psychology
Sammanfattning : Aposematic species have evolved conspicuous warning signals, such as bright colors and striking patterns, to deter predators. Some edible and harmless species take advantage of this deterrent effect by mimicking their appearance. Mimicry is a great example of how natural selection produces remarkable adaptations. LÄS MER
2. Individual variation in behaviour: personality and performance of brown trout in the wild
Sammanfattning : Individuals from the same population often show very different behaviour. These differences, when consistent across time, are referred to as animal personality or behavioural syndromes. Explaining the occurrence of animal personality from an evolutionary perspective has however proven a difficult issue to tackle. LÄS MER
3. Predator psychology and mimicry evolution - a theoretical analysis
Sammanfattning : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. LÄS MER
4. Colour patterns in warning displays
Sammanfattning : In aposematism a prey species use bright colours, often combined with a black contrasting pattern, to signal unprofitability as prey to potential predators. Although there are several different hypotheses about the presence of these internally contrasting patterns, there is little experimental evidence of any beneficial effects. LÄS MER
5. Hippocampal circuit dynamics in learning and value processing of sensory cues : A study into the function of hippocampal microcircuits involving OLMα2 cells
Sammanfattning : The anatomical signatures of the mnemonic/emotional processes share many brain structures, one of which seems to constitute a bridge, the hippocampus. It functions as a structure that consolidates engrams. It is connected to the prefrontal cortex, nucleus accumbens and amygdala, structures that provide emotional salience. LÄS MER
